  • CRTs have been widely used as TV displays and excel in resolution and picture quality.
  • the depth and weight increase as the screen size increases. Solution of this problem is a key to the production of large-screen CRTs. Therefore, it is considered that producing CRTs having a large screen size exceeding 40 inch is difficult.
  • LCDs have found wide spread use as monitors for computers due to excellent characteristics such as smaller power consumption, size, and weight than CRTs.
  • large-screen LCDs have such technical problems to be solved as faint images and disordered gray-scale levels or color gradations which are caused because LCDs themselves do not emit light when displaying images.
  • a defect of narrow viewing angles which is unique to LCDs, must be cleared in order to achieve large-screen LCDs.
  • PDPs unlike CRTs or LCDs, PDPs have an advantage that large-screen PDPs can be achieved with relatively small weights. Also, PDPs have a merit that they consume smaller electricity in spite of the driving method in which PDPs themselves emit light for displaying images. Therefore, at the present time when next-generation displays are sought for, large-screen gas discharge panels such as PDPs are especially studied and developed eagerly. Gas discharge panels with a 50-inch or more screen have already been developed.

  • the above resistance can be adjusted by changing the amount of oxygen contained in the electrically conductive oxide.
  • other materials of high resistance may be used, such as thin ITO.

  • the present invention is characterized by the first discharge gap width and the second discharge gap width formed between a plurality of display electrodes.
  • the discharge gas and the discharge gap width are related to each other as product p ⁇ d, where p represents a filling gas pressure (Torr) and d represents a discharge gap width (cm) (refer to “Electric Display Device”, Ohm Company, 1984, pp113-114). Therefore, first, a plot of discharge start voltages Vf vs. product p ⁇ d and a plot of discharge efficiency (relative value) vs. product p ⁇ d are created. Appropriate ranges of product p ⁇ d are then selected from the plots. From the selected ranges of product p ⁇ d, the percentage of Xe in the discharge gas is determined. The discharge gap width is also determined from the selected ranges of product p ⁇ d.

  • discharge sustain voltages Vm Applied voltages measured when the light vanished after the applied voltage had gradually been decreased after the discharge had become the sustain discharge were recorded as the discharge sustain voltages Vm. Relative-values of discharge efficiency were calculated using each discharge sustain voltage Vm, and with the relative values of discharge efficiency on the vertical axis and the product p ⁇ d on the horizontal axis, a functional curve (discharge efficiency curve) showing a relationship between the relative value and the product p ⁇ d was obtained. Each discharge efficiency value was calculated using Formula 1 shown below, where Vm represents discharge sustain voltage, I discharge current, L luminance, and S light emission area.
  • the Paschen's curve is a downward curve, and the discharge efficiency curve is an upward curve. These curves have peaks respectively being the minimum value Vf min of the discharge start voltage and the maximum value of the discharge efficiency.
  • Two product p ⁇ d values are determined from the above two kinds of peaks. Then, a proper range of the product p ⁇ d for manufacturing an actual PDP is determined from the two product p ⁇ d values. Accordingly, a point to be checked first in determining the product p ⁇ d is how clearly the peaks are detected from the curves.
  • the Paschen's curve and the discharge efficiency curve with the above shapes are obtained when discharge gases other than the Ne—Xe base discharge gas are used. Also, it is known that the above two curves are obtained in terms of, for example, partial pressure (P xe ) for the Xe gas in the discharge gas when a discharge gas containing a plurality of elements such as the Ne—Xe base gas.

  • FIGS. 24A, 24 B, and 24 C show the discharge efficiency curve.
  • FIGS. A, B, and C of these figures respectively correspond to cases where the percentage of Xe in the discharge gas is 5%, 10%, and 2%.
  • a relatively acute curve is included in the range of 1 to 5 (Torr ⁇ cm) of product p ⁇ d determined from a range including Vf min . It is also noted that a clear peak is in the range of 2 to 4 (Torr ⁇ cm). The range of the product p ⁇ d determined from the peak may be narrowed to 2.5 to 3.5 (Torr ⁇ cm). In addition, the discharge start voltage Vf is lower than 200 V in a region around the peak.
  • a similarly shaped curve is shown in the Paschen's curve in FIG. 23B when the percentage of Xe in the discharge gas is 10%. However, in this case, a range of product p ⁇ d with smaller values (approximately 1 to 3 Torr ⁇ cm) is determined from the peak.
  • Ne—Xe base discharge gas appropriate percentages of Xe in the Ne—Xe base discharge gas are 5% and 10%.
  • 5% or 10% of Xe is selected.
  • Many of generally used Ne—Xe base discharge gases contain approximately 5% of Xe. Accordingly, it is considered that a discharge gas containing 5% of Xe is most appropriate in manufacturing the PDP of the present embodiment.
  • product p ⁇ d suitable for the minimum value Vf min of the discharge start voltage Vf (and the first discharge gap width) can be arranged in the following order of desirableness in accordance with the ranges determined from approximately the peak of the Paschen's curve.
